“I don’t understand Jared Kushner at all. What is he doing? He’s turning his back on his religion and his heritage just so he can make money? I don’t get it. I just can’t wrap my mind around it,” Reiner, who is Jewish, told The Daily Beast in an interview published over the weekend.

Kushner is a modern Orthodox Jew. His wife, Ivanka Trump, converted to Judaism under Orthodox auspices to marry him.

Reiner, who also is a Democrat and publicly supported Democratic presidential nominee Hillary Clinton, said Kushner’s brothers-in-law, Eric Trump and Donald Trump Jr. retweeted memes from anti-Semitic websites and welcomed support from anti-Semitic and racist groups during the presidential campaign.

“The whole time while all those anti-Semitic memes were being passed on throughout the campaign, [Trump] certainly must have known, and his sons Eric and Don Jr. must have known they were retweeting things from anti-Semitic websites,” Reiner said.

“Even if you want to cut them all the slack in the world, they have never to this day said, ‘This is absolutely unacceptable and abhorrent that we are being supported by these groups of people.’ They’ve never said it! So they’re completely comfortable with the idea that anti-Semitic and racist groups are supporting them.”

In an interview with The Daily Beast Thursday, Reiner said of the fortune Bannon made from investing in the TV show “Seinfeld,” which Reiner’s production company participated in, “It makes me sick.”
